Description

[Detailed description of the invention] Industrial application field The present invention is a wall-embedded air conditioner T1k (hereinafter referred to as an air conditioner).
Regarding drain drainage equipment.

BACKGROUND OF THE INVENTION In recent years, there has been an increasing demand for drain drainage devices for air conditioners to be easy to install and serviceable.

Conventionally, as shown in FIG. 4, in a drain drainage device for an air conditioner of this type, an indoor heat exchanger 22 is attached to an air conditioner main body 21 inserted into a mounting wooden frame 20. When the air conditioner main body 21 performs cooling operation, dew condenses on the heat exchanger 22 and drain water drips, so a drain pan 23 is installed below the heat exchanger 22. Furthermore, the flexible drain hose 24 is inserted into the drain hose attachment part 26 provided at one end of the drain pan 23, and the other end of the drain hose 24 is inserted into the drain pipe 27 buried inside the wall 26 to drain the drain water out of the machine. It was intended to lead to.

In such a conventional air conditioner drain drainage device, drain water is drained from the drain hose attachment part 26".
The drain hose 24 connected to the wall 26
Either the drain hose 24 is inserted into the drain pipe 27 buried inside the drain pipe 27, or the drain hose 24 and the drain pipe 27 are connected in advance and then the drain hose 24 is inserted into the drain hose attachment part 26. In the case of the former connection work, wall 2
6, or through the inside of the mounting wooden frame 2o while holding the air conditioner main body 21, and the latter connection work must be done in a narrow place inside the air conditioner main body 21. Construction work was to be carried out, and in both cases, the workability was not good, and therefore the serviceability was also not good.

The present invention solves the above-mentioned problems, and its primary purpose is to improve the workability of connection work and to prevent water droplets from scattering. In addition, even in construction work that requires pumping drain water once, the second priority is to make it possible to pump water.
The purpose is to

Means for Solving the Problems In order to achieve the first object, the present invention includes a drain pan provided at the bottom of a heat exchanger, one end of which is connected to the drain pan, and an air conditioner main body is inserted into the outer end of the drain pan. The drain pipe is positioned in advance at the rear of the mounting frame and led out of the machine, and the saucer and strands are installed at a position directly below the outside end of the drain hose when the air conditioner main body is fixed to the mounting frame. The first means of solving the problem is to connect the drain pipe to the piping connection port provided at the bottom of the saucer. In addition to the above-mentioned first problem-solving means, in order to achieve the second objective, a plug is provided at the drain pipe connection port, and a drain pump is installed in place of the drain drain pipe in the space above the plug. This is the second problem-solving method.

Function The present invention has the above-mentioned first problem-solving means, so that when the air conditioner main body is fixed to the mounting frame, the saucer is located directly below the outer end of the drain pipe whose one end is connected to the drain pan. When the air conditioner is operated for cooling and drain water is generated, it is led out of the machine from the drain pan through the drain pipe, and the water that drips onto the outside end of the drain pipe is received by a saucer and drained. Further, according to the second problem solving means, the drain water stored in the drain pan can be pumped up by operating the drain pump, and the slope required for drainage can be sufficiently obtained.

EXAMPLE Hereinafter, an example of the first invention will be described based on FIGS. 1 and 2.

As shown in Fig. 1, the air conditioner body 1 has an indoor heat exchanger 2.
A drain pan 3 is provided at the bottom of the heat exchanger 2. A drain pipe 4, which is a hard pipe made of vinyl chloride or the like, is connected to the drain pan 3, and drain water is led out of the machine. The outer end 4a of the drain pipe 4 is provided at a predetermined position on the back side of the air conditioner main body 1. Therefore, when the air conditioner main body 1 is fixed in contact with the mounting frame 6 provided by opening the wall 5, the connection between the mounting frame 6 and the drain pipe 4 is
The position adjacent to the layer outer end 4a is also determined. The saucer 7 is installed by fixing it to the mounting frame 6 at a position directly below the outer end 4a of the machine, and a piping connection port 9 is provided at the bottom 8 of the saucer 7 as shown in FIG. A drain pipe 1o is connected to the port 9. A tapered plate 11 is provided on the bottom 8 of the saucer 7, and the outer end 4a of the drain pipe 4 is positioned directly above the tapered plate 11.

In the above configuration, when dew condenses on the heat exchanger 2, it is drained from the outside end 4a of the machine through the drain pan 3 and the drain pipe 4, and drips onto the tapered plate 11 of the saucer 7 provided below, without being scattered around the saucer 7. After that, the water is drained into the drain pipe 10. Further, when installing the air conditioner main body 1, there is no need for hose connection work, which improves workability and serviceability.

Next, an embodiment of the second invention will be described based on FIG. 3.

As shown in the figure, a pipe connection port 9 provided at the bottom 8 of the saucer 7
At the same time, a stopper 12 is installed in the drain pipe 40 to close it off, and the drain pipe 40 is located under the outer end 4a of the drain pipe 40 (at a position away from the -plate t).
The drain pump 14 is attached to the side surface 13 of this saucer 7 above the dowel plug 12 using a fixture 15 attached to the drain pump 14, and the drain pump drain pipe 16 is used to pump up water by -100 degrees, and then the slope is sufficiently adjusted. I try to drain it.

The above configuration can be used when it is necessary to pump drain water upwards and then drain it into a main drainage pipe (not shown). Splashing is prevented, and by using the space above the plug 12 and providing the drain pump 14 with the fixture 15, drain water can also be pumped up.

Effects of the Invention As is clear from the above embodiments, according to the first invention, a saucer is provided in advance under the outer end of the pre-positioned drain pipe, so that installation of the air conditioner body is simplified. In some cases, there is no need to connect the conventional drain hose and drain piping at all, improving workability and serviceability.Also, since the saucer can be made large enough for the diameter of the drain pipe, there is no misalignment during construction. is easily absorbed. Furthermore, according to the second invention,
It is also possible to attach a drain pump to the saucer, making it possible to pump up drain water even during construction work that requires pumping up drain water, which has extremely practical effects.
